In critiquing someone else's theory, learners share insight into their own understanding of mathematical concepts. Fifth graders will explore the notion that products are always larger than their factors. While this statement is true the majority of the time, fractions create the reverse effect on numbers. The end result of the activity is for learners to evaluate the statement and examples on the worksheet and to express their thinking clearly and precisely.
